Correspondence Abstract Y.J. Bae, Division of Life Science, College of Life Sciences and Biotechnology, Six species of Megaloptera in the families Sialidae and are recognized Korea University, 145 Anam-ro, in Korea including one new species (Sialis koreana, n. sp.), two species (Sialis Seongbuk-gu, Seoul 136-713, Korea annae Vshivkova and Sialis longidens Klingstedt) new to Korea, and three species E-mail: [email protected] (Neochauliodes formosanus (Okamoto), Parachauliodes asahinai Liu, Hayashi & Yang, and Protohermes xanthodes Navás) previously recorded in Korea. Descrip- tion of the new species, diagnoses of all known species, illustrations and photographs of diagnostic characters, photographs of habitats, key to the species for male adults, and taxonomic remarks are provided.

Introduction are found in lotic and lentic habitats with soft sediments. They do not feed during the adult stage for one or two weeks, The order Megaloptera is composed of two families, but the larvae of both Sialidae and Corydalidae are active Sialidae and Corydalidae, wherein the family Corydalidae predators on small invertebrates including other aquatic includes subfamiles Corydalinae and Chauliodinae. The order . consists of 328 extant species worldwide including 81 Siali- In this study, we reviewed previously known species of dae species, 131 Coydalinae species, and 116 Chauliodinae Megaloptera in Korea and provided description of one new species (Cover & Resh, 2008). Because of their large body species. size and relatively low agility, members of this order are relatively well known (Glorioso, 1981; Whiting, 1994; Liu & Yang, 2006b; Liu et al., 2007, 2008, 2010).
